With years of experience in feed machinery, combined with the most advanced cooling technology in the world. Zhengzhou Fusmar Machinery manufactured a new generation of cooling equipment – SZLH series counter flow cooler, mainly used for cooling high-temperature pellets after pelletization.

New Type Cooler

The counter flow cooler is a new type of cooler, it is popular in the world. It uses the principle of counter current cooling to cool the high temperature and high humidity pellets. That is, the ambient cold air passes vertically through the layer and first contact with the cold material. The hot air is in contact with the hot material, and the airflow direction is opposite to the flow direction. So that the pellet material gradually cooled in the forward direction.

The cooler can prevent directly contacted with the cold air and the high-temperature pellet materials, avoiding the surface cracks of pellets. Since the cold air enters the cooler from the bottom in all directions, the air inlet area is large, and the cold air utilization rate is high. Therefore, the cooling effect is remarkable, and the machine has low energy consumption and simple operation. So the counter flow cooler is superior to the previous vertical and lying, it is a new generation of cooler.

Cooling Effect Of The Machine

When the pellets coming out of the feed pellet machine pass through the cooler, they are in contact with the surrounding air. As long as the atmosphere saturated, moisture carried away from the surface of the pellets. The moisture inside the pellets moved to the surface, and the moisture evaporation separated from the pellets. The pellets are cooled. At the same time, the heat absorbed by the air heats the air. This improves the water carrying capacity of the air, and the fan continuously discharged the air. Taking away the heat and moisture of the particulate material in the cooler.

High Quality Counter Flow Cooler

Counter flow cooler is a new type of cooling machine which is advanced in the world. It uses the principle of counter current cooling to cool high temperature and high humidity pellets. The ambient wind passes vertically through the material layer, firstly in contact with the material layer, and the hot air gradually becomes in contact with the hot material. The airflow direction is opposite to the flow direction so that the granular material gradually cooled in the forward direction. Thereby avoiding cold air and high-temperature granular materials, avoiding direct contact to cause cracking of the pellet surface. The pellet cooling is sufficient and uniform and the unique sliding valve vibration makes the mechanical discharge, smooth operation, smooth shaking, and the pellet temperature after cooling is not higher than room temperature 3-5 °C.

  1. It has the unique function of automatic pelletizationduring the shutdown to avoid cross-contamination between feeds.
  2. Use a unique discharge frame to force the discharge.
  3. Cooling evenly and low degree of fragmentation.
  4. The structure is simple, the operation cost is low, and coverspace is small.

Why Choose Counter Flow Cooler

  1. The machine has a unique cooling mechanism, the cooling wind and the pelletmaterial move in the opposite direction. So that the material gradually cooled from top to bottom. Avoiding the surface cracking of the particle caused by the general cooling of the vertical cooler, the moisture and heat in the heart are difficult to dissipate and fragile during the cooling time, etc disadvantages.
  2. The use of the vibration locking device improves the cooling effect, reduces the pelletbreakage rate. Eliminates the disadvantage that the cooler cannot work after the pellets become hard, and reduces the power consumption.
  3. The cooled material temperature is not higher than room temperature +5 degrees Celsius. And the precipitation rate is not less than 3.8%. Which plays an excellent role in producing high-quality pellet feed, prolonging the storage time of pellets and improving economic benefits.
  4. The output is large, the cooling effect is good, the degree of automation is high, the noise is low, and the maintenance is small. The feed pellets manufacturer widely uses this machine, which is an advanced replacement type cooling device.

Choosing a suitable feed cooling machine and using it properly will significantly improve the quality of the feed. It will soon reflect a benign effect in the production process. If you can further master the technology of cooling, you can also greatly reduce the cost of materials, thereby increasing profits.
